Halo 3, Tsavo Highway on legendary hacks and cheats

Tsavo Hwy on Halo 3 has a few cheats no one knows of. Thought I would share. 4 caves and 3 sections of Tsavo Hwy. Bungie divided it into two sections. I got through it on legendary in 90 minutes with these cheats. Without stopping to explain things I can get through it in an hour.
The fuel rod cannon firing from nowhere that I thought was a glitch I later found a brute firing it from a hidden location.
